Autoimmune Not On Brainscape Flashcards

1
Q

How does autoimmunity occur

A

Breakdown of central tolerance
- failure to delete auto reactive t or B cells

Breakdown of peripheral tolerance

  • regulatory T cell deficits
  • impaired immunomodulation
  • altered self antigens

Activation of auto reactive B cells

  • T cell independent activation
  • carrier effect
